Simulation of Highly Reflective GaN/AlxGa1-xN Distributed Bragg Reflector Structure for UV-Blue LEDs
(AMER SCIENTIFIC PUBLISHERS, 2018)
In this study, we showed theoretically enhanced reflectance characteristics of nitride based blue Light Emitting Diode (LED) by adding GaN/AlxGa1-xN Distributed Bragg Reflector (DBR) between n-contact layer and GaN buffer ...
Two-step passivation for enhanced InGaN/GaN light emitting diodes with step graded electron injectors
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2018)
Enhancement of InGaN/GaN based light emitting diode performance with step graded electron injectors through a two-step passivation is reported. Perimeter passivation of LED dies with SiO2 immediately following ICP mesa ...
InGaN stress compensation layers in InGaN/GaN blue LEDs with step graded electron injectors
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2018)
We investigate the effect of InGaN stress compensation layer on the properties of light emitting diodes based on InGaN/GaN multiple quantum well (MQW) structures with step graded electron injectors. Insertion of an InGaN ...
Microstructural Evolution of MOVPE Grown GaN by the Carrier Gas
(PLEIADES PUBLISHING INC, 2018)
We report the effect of total carrier gas flow of GaN during both GaN nucleation layer and high temperature GaN growth steps on structural, optical, electrical and morphological properties. The formation of dislocations ...
